Press-Fit Evaluation and Study of Displacement in Temperature Changes

Abstract

The article is devoted to bearing analysis, which has a specific shape. The outer ring is the body directly and the inner ring is the case. To determine optimal radial clearance or overlap are used the thermal / structural analysis. The article is logically divided into two parts. In the first analysis, was monitored the impact of the press-fit of the case into the body. In the second analysis, there are presented attained results in graphical outputs of displacements in the orbits at different operating temperatures. At the end of the article were evaluated and researched individual effects on bearing deformation.
